Corneal abrasions are eye injuries that result from having a trauma to the eye. A corneal abrasion is a scrape or scratch to the surface of the clear part of the eye. The cornea has many nerve endings, therefore an abrasion tends to be painful and causes the eye to become red and teary.
The cornea is an integral part of your vision, and it is necessary to seek eye care in the event that you have a corneal abrasion. If left untreated, a corneal abrasion or laceration can become infected and permanently damage your vision.
